6- ATTORNEYJ H. SLAVlN WINDOW CLEANING DEVICE Flled Aug 21 1947 July 22, 1952 4 1." Thisinvention relates to window cleaning devices; and particularly to improvements in'win' dow cleaning devices capable of simultaneously cleaning the opposite sides of a window pane.

.An important object ofthis invention'isto provide animproved device for cleaning and washing windows and similar surfaces, and particularly to an improved manually operated device adapted for simultaneously cleaning and washing both; the inside and the outside surfaces of the window pane without requiring theloperator to leave the room side ofthe window An impore tantobject of the invention is to provide such a device including an improved handle thereon capable when grasped by the hand of the'u'ser to not only move the device over the window pane surface, but to also exert simultaneous pressure by the cleaning elements of the device lipo'n'the window pane, which pressure can'Ibe varied by the compression with which the hand 'of the operator grips the handle. A furtherobject of the invention is to provide an improved device 'of this character which is simple and efiectivefin operation, and which is constructed of parts "ca 'pable to bein manufactured and assembled'at lowcost. V v Incarrying out'th'e invention, the novel handle is so constructed that the device may be gripped by one hand and moved over the window pane area'andv atthe'same time engage the window a WINDOWcm N ivennvirffi l 1 i i r rs r airtim v Application iiugustizl, v

ciated cleaning element 20 laterally relative to acteristics and so formed as to project beyond the opposite ends of section 32. The opposite projecting ends of the strap 34, referred to at; 3636, are bent'or' curved toward the arm I2 and contact or bear upon the outer face of the arm. Preferably, these projecting end portions I I tightly gripped by the operator to force the cleaning elements into engagement with the winfollowing their contact with arm I 2 are curved outwardly away therefrom as indicated-in 1 and 2. Suitable means, such as the 'screws members '33 may be employed to secure the intermediateportion of the strap 34- tothecIose'd- Normally, resilient end portions 7 I end section 32.

of the strap 34 will actto space the dosed end section 32 away from the arm I2 and thus draw the cleaning element away from the opposing cleaning element 16,: When in use upon a windpw pane, as will be described in more detail hereinafter, the position of the parts illustrated in full lines in Figs. 1 and 2 will occur, thus bringing the two cleaning elements into substantially juxtaposed relation.

" The metal strap 34, in combination with the closed end section 32 and the arm I2, forma handlewhich is grasped by the hand of the op-' erator; When'the handle is tightly gripped or squeezed, the'intermediate portion of the strap 34 and the arm I2 are moved toward one another againstthe yielding resistance of the projecting end sections 36-36 and assume the position shown in'Figs. '1 and 2. As a result of this squeezing action; the cleaning element 20 is moved by member'24 toward the opposite cleaning element I6. In use, the U-shaped structure formed by arms I0 and I2 and the closed end I4 thereof is mounted in a window opening so that the arms overlap upon opposite sides of a window sash indicated at 40'; The wiping'elements are brought into position on oppositesides of the 7 window pane'42 and when the handle is tightly gripped'by' theoperatorythe cleaning elements I6 and 20 will :be compressed into engagement with the opposite surfaces of the window pane, The dotted outline of the device Fig. l illustrates an initialposition of the parts prior to the squeezing operation. Thereafter, upon squeezing'oif the handwhich grasps the handle, the framemember 24 will be moved'inwardly toward the window pane and into engagement therewith;

In the operating position, it is desirable to lock the cleaning elementsjn engagement with the window pane. For, this' purpose, there provided a releasabl locking detent comprising a plate member 44 which hinged 'at 46-tothe edge of; one of the side sections of the member 24.-- The plate 44 is provided with two downwardly turned flanges 48 and 50 which, when .thedetent is swung to the position indicated-in Fig; 2, will. overlap upon the strap.34,and the s1} spring is" illustrated 'as being in thefform its extremities respectively bearing against the adjacent side of the member 24 and against the dowpane, the detent may be allowed to return to its locking position, holding these elements in close engagement with the pane.

Fig. 3 illustrates a modification of the invention wherein there is substituted for the cleaning elements I6 and 20, wiper blades 55 and 58. These blades are preferably formed of resilient material, such as rubber, and are mounted respectively upon base members fifl and 62", which inturn, are'secured to the inner faces of the arms Ill and I2. Theuse of the device of Fig. 3 is similar to the embodimentof the invention previously described; i

What'I claim is: 1. A window cleaning device comprising, in combination, a pair of arms extending in spaced generally parallel, relation to one another and joined at one of their endsto form a U-shaped s pporting structure, a window cleaning element fixed to the outer free end of one of saidarms,

a second window cleaning element carried-on the outer free end of the other arm in opposed relation to the fixed cleaning element and-mounted on the arm for movement toward and away from the fixed element, a handle secured'to said mov able? cleaning element and; having a portion thereof cooperating with the adjacent arm to form a hand grip, said handle and said portion of the arm acting to thrust the movable cleaning element toward the 'fixed cleaning element when tightly gripped by the hand, and means yieldingly resisting such movement of the movable cleaning element. f

2. A windowv cleaning device comprising, in combination, a pair of arms extending in spaced generally parallel relation to one another and joined at one of their .ends to'form a. Urshaped supporting structure, a window cleaningelement fixed to the outer free endof one of said arms, a second window cleaning element carried on the outer free end of the other arm in opposed relation to the fixed cleaning element and mounted on the arm for movement toward and away from the fixed element, a handlesecured to said movable cleaning element and having a part thereof extending in slightly spaced substantially parallel relation to thefree end of the arm upon which the movable cleaning element is carried and co.-

of awire' member"52fhaving'its'1intermediate f strum wrapped around hinge pin '54 and 5 operating with the latter toform a hand grip. said hand grip adapted when squeezed *byrha'nd jto bodily move the movablecleaning element'relative to the holder and toward'the fixedcleaning element, means yieldingly resisting such movement of the movable'cleaning element, and a releasable locking detent carried by the arm upon which the movable cleanin elementis mounted and engageable withthe handle to'locl; the element in the tightly gripped hand positioni ,3. A window cleaning device comprising, in

combination, a pair of cleamng elements adapted to be positioned on opposite faces o'f'a grasypane,

a substantially U-shaped holder for supporting and connecting said cleaning elements, one end of said holder being rigidly connected to one of said cleaning elements, the other end of said holder having a loose connection with the other cleaning element and providing limited movement thereof toward and away from the rigidly connected cleaning element, and a handle secured to said movable cleaning element and having a. part thereof extending substantially parallel to but slightly spaced from the adjacent end of the holder and cooperating with the latter to form a hand grip, said part and the adjacent end of the holder when tightly gripped by the hand of the operator adapted to bodily move the movable cleaning element relative to the holder and toward the other cleaning element to cause the two elements to compressively engage the opposite sides of a glass pane.
